Is there any Special Configuration in Exchange 2007 with Win 2008 especially for outlook any where configuration ISA 2006 publishing rule, I created simple publish ( Publish for non web Server ) rule that just forward the traffic to the exchange server without any special publish rule (i.e.: publish exchange server Rule), so is this correct or I have to use the Exchange publish rule for HTTP and HTTPs. I face now a problemwith outlook any where configuration and there is smth in the authentication but I don't know where is the problem is it due to mis-configuration in ISA Rule or the problem due to Exchange with Windows 2008 Best Regards, mwahab

Hi,For the Outlook Anywhere, please ensure the autodiscover.domain.com or domain.com are included in the Subject Alternative Name on the certificate. And you mustadd a host record for the Autodiscover service to your external DNS zone.The external host name for enabling Outlook Anywhereshould match the common name or FQDN used in the server certificate installed on the ISA Server computer.To public the Outlook Anywhere in ISA 2006, pleae refer to the below article for your reference.:http://www.msexchange.org/tutorials/Outlook-Anywhere-2007-ISA-Server-2006.htmlhttp://technet.microsoft.com/en-us/library/bb794751.aspxThanksAllen
